متن کاملSkolem Density Problems over Large Galois Extensions of Global Fields
Let K be a global eld, V an innnite proper subset of the set of all primes of K, and S a nite subset of V. Denote the maximal Galois extension of K in which each p 2 S totally splits by K tot;S. Let M be an algebraic extension of K. A data for an (S; V)-Skolem density problem for M consists of a nite subset T of V containing S, polynomials f 1 ; : : : ; f m 2 ~ KX 1 ; : : : ; X n ] satisfying j...
متن کاملGalois Extensions of Hilbertian Fields
We prove the following result: Theorem. Let K be a countable Hilbertian field, S a finite set of local primes of K, and e ≥ 0 an integer. Then, for almost all ∈ G(K)e, the field Ks[ ] ∩Ktot,S is PSC. Here a local prime is an equivalent class p of absolute values of K whose completion is a local field, K̂p. Then Kp = Ks ∩ K̂p and Ktot,S = T p∈S T σ∈G(K) K σ p . G(K) stands for the absolute Galois ...
متن کاملUNRAMIFIED EXTENSIONS AND GEOMETRIC Zp-EXTENSIONS OF GLOBAL FUNCTION FIELDS
We study on finite unramified extensions of global function fields (function fields of one valuable over a finite field). We show two results. One is an extension of Perret’s result about the ideal class group problem. Another is a construction of a geometric Zp-extension which has a certain property.
